Fortunately after 3 years of HRT and the fact that I did not have excess body and face hair previous to my transition, it seems that the HRT has significantly reduced just about all of my leg, arm and chest/stomach hair... I still have to tend to my thinning face hair every couple days or so...
For me, shaving is the best for my skin, all the other methods (even at a salon) I have tried seem to cause all kinds of irritation issues.
Because I am full-time, obviously any hair showing up in the wrong places is not a good thing.
